Approx. 3.8km path. "METAL SHINGLES TORN AND TWISTED OFF OF BARN ROOF. METAL AND WOOD DEBRIS THROWN HUNDREDS OF FEET ACROSS A ROAD AND DOWNWIND. A SMALL WOODEN SHED WITH PLASTIC TARP ROOF WAS DESTROYED."

[the following summary from EC:] TORNADO (PEAK WINDS BETWEEN 120 AND 180 KM/H) MOVED THROUGH AN AREA JUST TO THE NORTHEAST OF FEVERSHAM WHICH IS APPROXIMATELY 20 KM SOUTHWEST OF COLLINGWOOD. A LARGE BARN HAD ITS ROOF TOTALLY REMOVED AND THREE SMALLER BARNS OR SHEDS TOTALLY DESTROYED. ONE OF THESE SHEDS WAS CONSTRUCTED OF CINDER BLOCKS. THE DAMAGE PATH WAS RELATIVELY NARROW APPROXIMATELY BETWEEN 40 AND 80 METRES WIDE AND THE MOST SIGNIFICANT DAMAGE WAS LESS THAN 1 KILOMETRE IN LENGHT. ONE OF THE INDICATIONS THAT THE STORM WAS TORNADIC WAS THE TOTAL LACK OF DAMAGE DONE TO A FARM HOUSE NEAR THE BARN THAT LOST ITS ROOF AND RESULTED IN THE SCATTERING OF BARN DEBRIS IN DIFFERENT DIRECTIONS AROUND IT. SOME DEBRIS FROM THE BARN AND SHEDS WAS CARRIED HUNDREDS OF METRES FROM THEIR ORIGINAL LOCATION. SOME TREE DAMAGE WAS ALSO NOTED BUT WAS NOT EXTENSIVE. AN EYEWITNESS TO THE STORM MENTIONED THAT VERY HEAVY RAINS PRECEDED THE EVENT FOLLOWED BY WINDS WHICH SHOOK HIS HOME. THE WORST OF THE WIND WAS OVER IN SECONDS AND WHEN THE WITNESS LOOKED OFF TO THE NORTHEAST IMMEDIATELY AFTER THE STORM HE BELIEVED HE SAW A FUNNEL CLOUD MOVING OFF. THIS WAS THE 12TH CONFIRMED TORNADO OF THE SEASON IN ONTARIO. ONTARIO NORMALLY GETS 14 TORNADOES EACH SUMMER DURING A PERIOD FROM LATE APRIL THROUGH TO EARLY OCTOBER.

2005:
Thunderstorms by Month
Before only a colour was used to designate a severe thunderstorm warning, but many times a warning was issued accompanied by only a weak storm. So in previous years I've kept records it was hard to tell if the storm was in fact severe just by looking at the table. An "X" will be placed into the box for thunderstorms if a warning was issued by Environment Canada but no severe t-storm actually occurred, and a "T" into the box if a tornado warning was issued without a tornado actually occurring. Warnings are defined as "imminent (ie: they WILL occur) or already occurring". For notes about a storm or a storm watch/warning, a number "eg: 01" will be placed in the box - see the note for that number at the bottom of the table. Or see the table above for more info and links.
